49. I'm not sure that that's really a difference at all

In my entire life I have never seen a Barbie ad with a boy in it or a GI Joe ad with a girl in it. I'm not even sure that I've ever seen a HotWheels or Matchbox ad featuring a girl.

Although they seldom specifically say "for girls," these products are undeniably marketed along predictable gender lines, to the point that the distinction between "targeted" and "marketed" is trivial and academic. Even if the manufacturers don't target boys or girls specifically, the retail stores certainly do.

In short, the absence of an explicit "girls only" or "boys only" label is simply a technicality, in the same way that we might say that our society is race-neutral because we don't have "whites only" water fountains anymore.
